SPECIFICATION forming part of Letters Patent No. 692,839, dated February 11', 1902.

Application tiled March 24, 1900.

To a/ZZ whom it may concern:

Be it known that we, SIMEON E. FARRADAY, a citizen of the United States, residing at Gloucester City, in the county of Camden and State of New Jersey, and JOHN H. Goss, re-

siding at the city of Waterbury, in the county of New Haven and State of Connecticut, have jointly invented certain new and useful Improvements inV Hydrocarbon-Burners, of Io which the following is a specification. Y

The object of this invention is to provide an efficient and comparatively inexpensive burner which shall be composed of few parts, simple in construction and application, said t 5 burner having a series of subburners arranged to communicate directly with the mixing-chamber, whereby the vaporization of the oil goes on uninterru ptedly when the lamp is in use irrespective of whether or not there 2o is a flame at the main burner; and to these and other ends hereinafter set forth the in- Vention consists of the improvements hereinafter described and claimed.

The nature, characteristic features, and 2' 5 scope of the invention will be more fully understood from the following description,taken in connection with the accompanying drawings, forming part hereof, and in which- Figure lis a central sectional view of a o burner embodying features of our invention.

Fig. 2 is a sectional View taken on the line 2 2 of Fig. l, and Fig. 3 is adetail View of the upper portion of the burner in section.

In a burner embodying features of the in- 3 5 vention there is a solid body portion d, which may be cast or otherwise formed in one piece and which is provided at its upper extremity with an annular recess which forms part of a vaporizing-chamber h. Extending through 4o the center of this body portion a there is formed an opening which is the mixing-chamber c. Located at the upper end of this opening is a tapered and threaded recess adapted to receive a cap d, which is provided with the '45 ordinary gauze, over which the mantle or in` candescent is suitably mounted. This cap d has a tapered shank correspondingly threaded to engage in the top of the mixing-chamber c and fits snugly onto the top of the body Serial No. 10,018l (No modelr) portion o, thus completing the vaporizingchamber.

e is a pipe provided with the usual filtering material, whichreceives the supply of oil or fluid fuel which escapes from it into a chamber b there is another passageL e2, also bored through the bodypportion, which may be termed the outlet-passage and which permits the discharge of the vaporized oil into the mixing-chamber; f

As is plainly illustrated in Fig. 3, slots, as fand f', are cut in recesses in the upper or circular head portion of the body ct, which slots permit of the escape of combustible material underneath the vaporizing-chamber b, where it is burned to heat the chamber.

At the lower end of the body portion a. there is the usual cup adapted to contain alcohol and the like used in starting the operation of the burner, together with a needle-valve for regulating the iiow of the fluid.

t is a casting provided with conduits, in this instance arranged in a right angle, and it is also provided with an extension j, which is fitted to the body portion a, and with another extension 7u. Onto .the part 7c is screwed a thimble .through which the threaded shank of the needle-valve works and which carries the cup.

, -Z is a nozzle-plug screwed into the casting t' and adapted to cooperate with the needlevalve.,

Inclosing the body portion ct is a shield g, which fits snugly around the same a'nd'may be brought into proper alinement by reference to the perforation which permits of insertion of the pipe e and also to the perforations which should come opposite the slots f and f'.

In use the alcohol in the .cup h is ignited. The burner is heated before oil is admitted to any part, even the part e. The flame from the cup and hot air rise through'the mixingchamber, thus heating the inside of the body portion a and also the vaporizing-chamber l), part of it escaping through the slots f and f and the remainder ascending through the mantle, thus vaporiz'ing the oil or uid fuel (which has meanwhile been admitted to the burner) sufficiently to start the flow of gas. The fluid fuel has now become vaporized and descends through the channel e2, issues from the nozzle entraining air, with which it mingles, and ascends through the mixing-chamber to the mantle, thus producing a mixture of air and vapor which burns beneath the mantle with a blue llame and also at the subburnersfandf. The subfiames atf and f vaporize oil at all times, so that if the mantle should be broken all the flames would burn, which would not be the case if the main llame were relied upon to do all of the generation.

It will be obvious to those skilled in the art to which the invention appertains that modifications may be made in details without departing from the spirit thereof. Hence We do not limit ourselves tothe precise construction and arrangement of parts hereinabove set forth, and illustrated in the drawings; but,

Having thus described the nature and objects of the invention, what we claim as new, and desire to secure by Letters Patent, is

l-. Ahydrocarbon-burnercomprisngabody portion having a bore or passage extending longitudinally thereof, which constitutes a complete mixing-chamber, and having in its top an annular groove or recess, a burner head or cap constructed. to cover said groove and forming therewith a vaporizing-chamber having inlet and outlet passages, said body portion having circumferentially-arranged slot-s located under said vaporizing-chamber and communicating with the mixing-chamber, and a shield surrounding the body portion and having openings arranged opposite the slots, substantially as described.

2. Ahydrocarbon-burnercomprisingasolid body portion having a central bore or passage extending the length thereof, which constif tutes a complete mixing-chamber, and having in its top an annular groove or recess, a burner head or cap constructed to cover said groove and forming therewith a vaporizingchamber and having a tapered tubular part or shank which is screw-threaded to fit a correspondingly-threaded portion of the mixingchamber, said vaporzing-chamber having suitable inlet and outlet passages, a vapordischarge nozzle or jet communicating with said outlet and having an axial discharge into the mixing-chamber, subburners penetrating the wall of the mixing-chamber at point-s subjacent said tapered part or shank and arranged to heat the vaporizing-charnber, and a shield or skirt secured to said body portion and encircling the discharge nozzle or jet, substantially as described.

3. Ahydrocarbon-burnercomprisingessentially two castings whereof one consists of a solid body portion that is provided centrally with a bore or passage constituting a complete mixing-chamber, and in its top with an annular groove or recess, and whereof the other consists of a burner head or cap constructed to cover said groove or recess and provided with a tapered tubular part or shank that is afforded a seat inside the mixing-chamber, said burner-cap and the walls of the groove conjointly forming a vaporizing-chamber, said vaporizing-chamber having suitable inlet and outlet passages, a vapor dischargenozzle communicating with the outlet-passage and arranged to discharge into the mixing-chamber from below thereof, subburners penetrating the walls of the mixing-chamber at points subjacent said tapered part or shank and arranged to heat the vaporizing-chamber, and a shield surrounding said body portion and encircling the discharge-nozzle having Ventilating-openings to accommodate the subburners, substantially as described.

In testimony whereof We have hereunto signed our names.
